kinda like when my race club ran track days, one of the "prep" items was to un-hook the wire for the AC clutch or pull the AC fuse before going on track, the WOT switch mode would disengage the AC under throttle ,, but re-engaging it when you got on the breaks would get you a LONG squeal until the engine RPM's got down under 4000. the clutches would be red hot after a couple laps.. And because of the fancy electronic temp controls in the cars, you could not totally disable the AC..AN interesting check,, BMW E46 models, have a nice duct system that looks like it could be repurposed for other applications, it forces air from a CAI through the alternator on the upsized packages for the car.. 2006 3 and I believe 5 series had one..

Alt pulley I'm using measures around 70mm wall to wall at the front, and the sidewalls have decent height.
So actual pulley diameter is around 65mm, or 2.5" or so. So not much larger than standard.

Does a belt slipping on the alternator have anything to do with any of this? 04 silverado 6500 rpm. Drive it nice and its fine. Drive it hard a couple times and there is belt dust all over the exit side of the pulley. New Delco tensioner and gatorback belt same thing.

But even an OEM alternator would run quite happily to 6800rpm for quite some time, as the very first unit I ever used did. I seen over 7k quite often with it. Although obviously not very often extended periods at high rpm.

The pulley on mine is larger than standard, so you would need to order whatever you want to order, and pulley sizes etc.
